It was mentioned a long time ago....but Tony Scott would be the ideal choice to direct - although he is very busy. I'd suggest there's a good chance Stephen Hopkins (Predator 2) would be in with a shout as he was initially involved with the launch of the original series and would be a steady hand rather than getting somebody unproven.

I love 24 as a series but am really not convinced that his should be made into a film. I think the idea should be binned. 24 works as a series because it is 24 episodes set in real time-ish. A 2 hour film just won't have the same feel and won't work

If this isn't going to get all ambitious and actually be 24hrs long then at the very least I hope they squeeze the whole day into the running time by applying some Benny Hill time capture. Complete with the music and scantily clad ladies chasing Jack Bauer all day.
